2 | dnl Process this file with autoconf to produce a configure script. | |
3 | dnl The ONLY thing this is used for is to configure for different | |
4 | dnl linux architectures and configurations, it is not used to make the | |
5 | dnl code more portable | |
6 | ||
7 | dnl You MUST have an environment that has all the POSIX functions and | |
8 | dnl some of the more populare bsd/sysv ones (like select). You'll also | |
9 | dnl need a C++ compiler that is semi-standard conformant, exceptions are | |
10 | dnl not used but STL is. | |
11 | ||
12 | dnl 'make -f Makefile startup' will generate the configure file from | |
13 | dnl configure.in correctly and can be run at any time | |
